For wireless routers and cable home gateways especially, this research shows that the total un-managed buffers in your system should be less than 32.Would it be a good thing to start describing these queues not so much in terms of packets but in terms of delay (or bandwidth X delay)?The unit of bandwidth is something like Mbps, that of delay can be second, so bandwidth X delay --> Mb, which is the unit of packet size. So both packets and delay should have the same effect for sizing buffers.
Bandwidth varies greatly with time. On cellphone, you can go from 5KB/sec GPRS to 300KB/sec HSDPA and back... Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
